A newfound bug in Google docs is causing it to crush and upon reopening it will crush again making it very difficult to re-access your document. The bug is manifested when a series of the same word is typed into a document and Show grammar suggestion is turned on.

How was it found
A Google Docs user, Pat Needham brought up the issue on Google Docs Editors Help forum.
"I've only tried in Google Chrome, with documents from three separate Google accounts (personal, G Suite Basic, and work one which might be enterprise). All three experience this same issue".
"It's case-sensitive. So trying with 'and. and. And. and. And.' doesn't cause it to crash."
While Needham publicly reported the bug, it appears that the issue was discovered by Eliza Callahan who was writing a poem novel for her novel using Google Docs.
Needham's findings have also been confirmed by other users running Firefox 99.0.1
Another user, Sergii Dymchenko, said strings like "But. But. But. But. But." triggered the same response. Some also noticed putting any of the terms like "Also, Therefore, And, Anyway, But, Who, Why, Besides, However," in the same format achieved the outcome.
A YCombinator HackerNews reader suspected the cause to be the "Show grammar suggestion" option in Google Docs.
A Google spokesperson confirmed the presence of the issue adding, "we're aware of this issue and the team is working on a fix."
How to recover your document
First thing first, turn off Show grammar suggestions so you do not run into issue by accident. In order to turn it off go to Tools and then into Spelling and grammar and untick Show grammar suggestions.
Now, if you already have a document that has been crushed, fear not because there is a workaround to access it. For some strange reason this bug does not manifest on Google Docs mobile app, so you can open the crushed document in the mobile app, delete words that have caused the bug and reopen the document on your desktop.
Until Google comes up with the solution this is currently the only way to address the issue.
When you are in settings, on the left side move toward the bottom until you run into a tab that says On Startup and click on it. On right, a new section will open, click on Open a specific page or set of pages.
You will be presented with the option to add a new page by typing its URL or getting it from bookmarks or using a specific opened one. You can repeat this process until you have added all pages that you wish to be automatically opened once Chrome is opened for the first time.

Once the menu appears, click on Command Prompt (admin)
Once the command prompt with administrator privileges comes on-screen type in it following string:
This command will force Windows to show all devices in the device manager including old ones that are not used anymore, but since their drivers are still installed, devices will show up.
When you type command press ENTER.
Once again press WINDOWS + X to show the hidden menu but this time choose the device manager
The device manager will open, go to view > snow hidden devices in order to show unused devices.
Right-click on the device and click on uninstall device to remove it completely from your system.
Please always be careful when removing devices so you do not remove the device which is being used by mistake and always double-check that you are removing something that you used to have on your system. This method will show all hidden devices even ones that are hidden but crucial to the system working properly.
